Filed: 1993-11-08
Abstract: PURPOSE:To constitute a seal device of perfect waterless, non-lubrication, and non-cooling, and enabling a non-contact type seal device to be applied for a vertical shaft pump. CONSTITUTION:When a main shaft 3 is driven so as to rotate a vane wheel 2, water in a water tank 5 is pumped up to a drain tank 8. At this time, the pressure of pressurized water is applied on the seal part of the main shaft 3. A labyrinth seal device 10 is used on the through part of the main shaft 3 from a casing 1 to a seal chamber 9c, and an air seal device 11 is used on the through part of the main shaft 3 from the seal chamber 9c to the outward. Further a leak water pipe 4 is connected to the bottom part of the seal chamber 9c, and the extreme end of the leak water pipe is sealed by water. Hereby although a waterless seal device with no necessity for water lubrication or the like is adopted, sealing of the main shaft at starting and during operation of a pump can be performed.

Title: Method for reducing information amount of image not requiring input on optical image input medium
Inventor: IDA AKIRA
IPC: H04N1/04
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To facilitate the decoding by displaying a background image not dropped out by an optical image reader onto a range on which images not requiring entry among images have been displayed without causing any gap. SOLUTION: Images 3 not requiring entry are images not needing reading such as a sentence 31 like a description notice or an explanation text, a graphic 32 like an explanatory graphic or logo mark, ruled lines 33 like frames of the sentence 31, and described items 34 of an entry column 2. In the case of reading an input medium 1 by an optical image reader by displaying a background image 4 onto a range on which images not requiring entry among images have been displayed without causing a gap, the image reader recognizes the range to be uniformly black levels. Thus, image data are remarkably compressed, the processing speed is improved and the decoding is facilitated by by displaying a background image 4 onto a range on which images not requiring entry among images have been displayed without causing a gap.

Title: Cross connection multi-rate/multi-cast sdh/sonet rearrangement procedure and cross connection using it
Inventor: PARK WON BAE
IPC: H04B10/27
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a connection procedure for finding out through rearrangement a path of a multi-rate/multi-cast traffic, via a synchronous digital hierarchy(SDH) cross connection having a sub-network connection protection. SOLUTION: In the case that an open path for a new payload passing through an SDH switching hardware is not available, a switching procedure seeks a path with a sufficient capacity that is blocked, based on an existing and smallest payload capacity. When a hunt is successful, the existing connection is allocated again in this procedure to execute a path with a new payload. This procedure does not interrupt the existing connection. Thus, this procedure is a 'hitless' procedure. An event of connection of an existing payload to be moved to produce a path for the new payload is entered in a queue, the connection produce is repetitively and sequentially applied to each until the queue is vacant.

Filed: 1987-12-03
Abstract: PURPOSE:To make the conditions of air and unburnt fuel flowing into an exhaust system of an engine properly adjustable by performing control over a fuel supply to remaining cylinder when fuel increment and supply restriction are both performed. CONSTITUTION:In an engine controller 12, a fuel increments means increases a quantity of fuel to be fed to each cylinder of an engine 10 and makes an air-fuel ratio at each cylinder into a rich mixture. In addition, a fuel limiting means limits a fuel supply to the specified cylinder on the basis of a slipped state of driving wheels to be detected in a traction controller 13. Here,when a fuel increment by the fuel increment means and a limit of fuel supply to the specified cylinder by the fuel limiting means are both performed, the control over a fuel supply to the remaining cylinders takes place. With this constitution, the conditions of air and unburnt fuel flowing into an exhaust system of the engine 10 are properly adjustable so that, for example, the overheat of a catalyzer 39 is prevented from occurring and durability in the exhaust system is thus improvable.

Title: Preparation of clarifying and deodorant component
Inventor: ISHIDA SHOJI
IPC: A61L9/01
Filed: 1987-12-02
Abstract: PURPOSE:To obtain a clarifying and deodorant component which maintains its semi- solid state over a long while and gradually releases its adsorbed component by making two or more kinds of highly hygroscopic resins adsorb a specific amount of stabilized chlorine dioxide and for preventing the resin from losing water. CONSTITUTION:Two or more different high water-absorbing resins are mixed to form a carrier; for instance, acrylic vinyl alcohol copolymer, which has enough gel strength to keep its shape after absorbing water, and sodium acrylate polymer, which has excellent instantaneous water-absorbing capacity and has power for absorbing water 1,000 times as its own weight, are mixed in the ratio of 1:10-10:1. Stabilized chlorine dioxide diluted with water to a desired concentration is held by adsorption on the carrier. Water used for dilution is physically processed; that is, it is exposed in a certain electric field 24 hours or longer to attain slow vaporization and to acquire high permeability. 50-1,000 pts.wt. diluted stabilized chlorine dioxide is held by adsorption on 100 pts.wt. high water-absorbing resins. A clarification deodorant component thus prepared includes high water-absorbing resins which do not discharge water once absorbing it, maintains its semi-solid state over a long while and gradually releases its adsorbed component.

IPC: G11B11/105
Filed: 1992-11-17
Abstract: PURPOSE:To improve a recording density by irradiating with a laser beam by double spotting in a magneto-optical recording and reproducing device. CONSTITUTION:A data is recorded by using two laser beams 1 and 2 whose second spot diameter is phiD2 obtained by a short wavelength laser diode 14, which is smaller than the first spot diameter phiD1 obtaind by a long wavelength laser diode 13. At this time, since a Curie temperature exceeds only in an area where booth spots are overlapped each other, the diameter of an irradiated area exceeding the Curie temperature becomes phiD2. Therefore, a recording density is heightened than that obtained when data is recorded basing on the spot diameter phiD1 obtained by a long wavelength laser diode 13 with sufficient optical power.
